A manufacturer uses two machines to produce connector pins. A quality engineer wants to compare the process capability of each machine. The engineer randomly samples five pins per box from each machine. The specification range for the length of the pin is 13 mm to 25 mm.
You can use this data set to demonstrate Normal Capability Analysis for Multiple Variables.
|Length||The length of each connector pin|
|Machine||The machine that produced the pin: 1 or 2|
